A CORPORATION OF DELAWARE: i

WINDOW.

Application filed June 10, 1926. YSerial No. 115,141.

rlhis invention relates to new and useful improvements in a window.

One object of the invention is to provide a window, including a casing and sashes mounted on the Casing in such a manner that the sashes may be readily removed or reversed so that they may be readily cleaned on both sides, from the inside of the room, and this without interfering with the window screen which may be permanently secured, if desired, to the outside of the window casing.

Another object of the invention is to provide a. window of the character described, whose lower sash is vertically slidable in the usual way to provide for ventilation at the bot-tom of the window and whose upper sash is pivoted in the casing, at its lower end, and Whose upper end may be swung inwardly and locked in open position to provide for ventilation through the upper part of the window.

A further feat-ure of the invention resides in the provision of novel means for locking the sashes in closed position.

` A still further feature of the invention resides in the provision of means for V'preventing the rattling of the sashes as well as means for forming water proof joints between the sashes as well as between the casing and sashes.

` The'invention also comprehends a novel construction of the sashes and casing whereby the sashes may he readily mounted in, or removed from'the casing.

Finally, an object of the invention is to provide a window of the characer described,

which is of very simple construction7 mayv be cheaply and easily installed and which is very eflicient in use.

lVith the above and other objects in 'view this invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this .speciiication and illustrated in the accompanyingl drawings, wherein: Y v

Referring now more particularly to the drawings wherein like numerals of reference designate similar parts in each of the figures the numerals 1, 1, designate the jambs of the casing, as a'whole, each casing having the head 2, and the sill 3. Each sill includes the outwardly declining ledge 4 and the inside stool 5 behind which the lower end of the lower sash 6 is adapted to tit when said sash is closed.

The inner face of each amb has a groove 7 in which the anchor blocks, as 8 are adapted to slide. The usual sash cords, as 9 are employed for the lower sash, only. The lower ends of the cords are inserted into the sockets 10 of the anchor blocks and are clamped therein by means of suitable clamp screws 11 to be screwed into the counter sunk holes 12 of said blocks. rl`hese cords work over the usual pulleys 13 set in the respective jambs and their other ends carry the sash balance weights 14 which are enclosed within the jambs in the usual way. 'lhere are lateral pintles 15, 15, carried by the upper end of the lower sash which work in the vertical vbearings 16, 16 in the inner sides of the upper ends of said blocks 8. The inner sides of said anchor blocks have long vertical bearings 17, 17, in which the lateral studs 18, 18, carried by the lower end ofthe lower sash 6, work.

Spaced above the stools 5 are the release grooves 19, 19, cut transversely across the inner faces of the blocks 8 and leading inwardly from the bearings 17. 'lhe lower sash may be elevated and lowered in the usual way through the sash litt 20 or 20 carried by said sash, the anchor blocks 8 running in the grooves 7. In order to reverse the lower sash the anchor blocks 8 may be locked against movement by the barrel bolts 22 carried by the jambs 1 and the sash 6 may then be elevated until the studs 18 align with the grooves 19 and its lower end then swung outwardly, said studs passing through said grooves 19 and saidlower sash may then be swung around on its pintles 15 and on into the position indicated in dotted lines in Figure 2 or removed from the casing by lifting until 'the pintles 15 disengage from the slots 15 in the block 8. lr desired the lower sash, and blocks 8, may be elevated to upper position and the sash then further elevated to discngagey the pintles 15 trom the slots 16 and the top oit' the lower sash, then swung inwardly on the studs 18 and this lower sash be thus reversed.

The upper sash 23 rests on the shoulders 24, 24, with its upper end l'itting closely against the lower edge oi the head plate 25. The outer side of the upper sash frame lits closely against the marginal weather strips 26 across the top and on the inside faces oi the casing.

In connection with the operation of the upper sash the construction of the easing should be particularly noted. The head 2 connects with the tace plate at the forward part of the window casino' as in the usual form, but the outer portion oi the head eX- tends downwardly below the level of the upper wall of the casing and the plate 25 reinforces the outer member of the head. rlhere is thus provided a wide clearance above the upper sash which, when the sash is swung'inwardly, perniits room for vventilation, as will be now described.

Fastened to the sides otl the upper sash frame at their lower ends, are the inwardly extending straps, or hook plates 27, 27, which embrace the lower sash and which have t-he notches 28, 28, in their upper edges, forming seats which receive the pintles 15.

Fastened to the head board 24, and extending inwardly, there is a flexible keeper plate 29. The upper end oi the upper sash carries a spring seated bolt 30 adapted to projectthrough a hole 31, in said plate to latch the upper sash in upright, or closed position. The ridge 29, on the under side of the plate 29, and a 'part thereof, presses down and outwardly against the inner topmost corner of this sash, holdingA it firmly against the stops 26 thereby preventing rattle.

It it be desired to reverse the upper sash the bolt 30 may be released from the bolt hole 31 and being held so released the upper sash may then be swung into the position indica-ted in dotted lines in Figure 3 .so that it may be easily cleaned. If it be desired to entirely remove said sash it may be lifted to disengage the notches 28 from the pintles 15 and immediately drawn inward to freedom from the casing. As clearly shown in Figure 13 there is a lengthwise slot 32 in the keeper plate 29, leading from the bolt hole 31 and the projecting end of the bolt 30 has the oppositely disposed notches 33, 33, so that by giving the bolt a quarter turn these notches will align with the edges of said slot and will thus release said bolt so as to permit the upper end oi the upper sash to be swung inwardly till thebolt reaches the inner end of the slot 32, thus providing for ventilation at the upper part of said window. rlhe bolt 30 may be manipulated by means of the ring 34 into which its power end is formed. rlhe projecting end of the bolt- 30 works through the angular bearingplate 35 carried by the upper end of the sash 23 and said bolt is seated on a coil spring 36, all enclosed in the tubular housing 37.

The outer end of the keeper plate has a transverse slot 38, cut therethrough, and adapted to receive the sash lift ot the lower sash to lock said lower sash in reversed position, as shown in Figure 2, and beyond said slot the tree end of the keeper plate 22 is upwardly turned, or beveled, at 39 so that when the `lower sash is reversed its lift, as 20, will strike against said upwardly turned end Sil and elevate the keeper 29 to permit the'en- Y' movement the barrel bolts 22 may be'engagedI in the bolt holes, as 40 in the anchor blocks 8. A special type of sash lock has been proj videdand. which may be usedfor locking the lower sash in closed position. This lock is shown in Figures 18 to 2l inclusive; it includes a casing 4l, which is set into the lower endy of the frame of the sash 6 and has the lateral wings 42, 42, which are fastened by screws to said sash frame. y

This casing 4l has a transverse bearing rod 43 whose ends are anchored to the sides oi' the casing and an arm 44 has its upper end pivoted on the rod 43 and its lower end is outwardly turnedforming an upwardly beveled bolt V45 which works through a bearing 46 in the inner side of the casing 4l.'

There isa release plate 7 whichforms a cover for the inner side of said casingl and whose lower end is formed into a plunger 48, which works between the arm 44, and the opposing wall of the casing" and operates against the upwardly inclined tace V49 of said arm. The upperend of theplate 47 works against the outer side. of the bearing flange 50 at the upperpend of the casing and has the inwardly extending sash lift 20 formed integrally therewith. The release plate has the inwardly extending lugs 5l, 5l, having the oblong vertical bearings 52, 52 which work on the rod 43. A pressure spring 53 has one end anchored to the rear wall of the casing 41 with its tree end pressing against the rear side of the arm 44 and normally holds the bolt 45 projected through its bearing 46. A keeper plate 54 is secured to the shelf 5 and the look bolt 45 normally engages with the keeper .to lock the lower sash in closed posiL tion. If it be desired to unlock and litt said sash an upward pull may be exertedon the lift 20 and this will operate, through the plunger 48, first to release the bolt 45 from its keeper, and then to elevate the sash G. and said sash may thereby be either further elevated in the casing. or reversed or entirely removed as hereinbefore explained.
